The present invention relates to a cotton gin for the purpose of cleaning bolly, dirty or snap cotton and is operated upon the suction principle which is used in bringing the cotton from the wagon to the gin` stand.

An important object resides in the provision of a structure which is simple, convenient in its arrangement ofl parts, thoroughly efficient and reliable in its operation and T o otherwise well adapted to the 'purpose for which it is designed. A

l/Vith the above and numerous other objects in View as will appear as the description proceeds, the invention resides in certain novel features of construction, and-fin Y the combination and arrangement of parts' asI will be hereinafter more fully described and claimed. f

1n the drawing:

Figure 1 is a vertical longitudinal section through the machine embodying the features of our invention,

Figure 2 s a vertical transverse section therethrough taken substantially on the line 2 2 of Figure l,

Figure 3 isa detail vertical section taken substantially on the line 3-3 of Figure 1,

Figure l1 is a fragmentaryv side elevation of one end of the machine,

Figure 5 is a plan view of the belt, and

Figure 6 is a bottom plan View of the separator.

Referring to the drawing in detail it will be seen that the letter H denotes an elongated housing consisting of side walls 5, a top 6,

- ally mounted on the inlet end of the partition for regulating the draft therethrough indicated by arrows 12. A screen separator cylinder 14 is mounted on a shaft 15 extending between the sides 5 and islocated imme- 13 diately adjacent the inlet I.

A plurality of shafts 16- are disposed between the side walls'5 under the partition 10 and on each shaft 16 is a gang of` disk sawsy 1.?. A separate plate .18 extends down# war'dly and rearwardly and has longitudi- 55 nally extending ribs 19 on the under surface thereof. A shaft 2O is mounted immediatelyy below the inlet eye and has sprockets'21-thercon. A shaft 22 is located belowV the seriesl of saws 17- adjacent the outlet O and has a sprocket 23 thereon.

Chains 211 are trained over the sprocket 23 and have a belt 25 therebetween with transverse cleats 26 spaced at regular intervals. rlll-he belt is trained' under the cylinder 111. A tensiony roll 27 is mounted between the sides 5 to engage the lower run of.-the`belt. A; spring pressed tensionV roll 28 is disposed between the sides to engage'the upper run ofthebelt immediately under the firstgang'of saws 17. Se i yA portion?" of the bottom?!inclinesdownf wardly and forwardly from v vthe'fendlwalilf"'9l and merges intoa cylinder 3OhavingI antentranceV slot 31 so that hulls rolling" vdowln the inclined slide. and' through slots T31' to'j enter' the cylinder 3O'andV are conveyed to one-*side by'an auger 32 journaled in the cylinder, one? Y end of the cylinder beingopen :to fori'n:amont-` let 33 as is clearly shown inFiIgi-igre'2'.1`

The belt carries the cotton under they saws and the cleats knock 4the hulls. olf thek saws. After the-belt'carries the hullls'or bollsso that'- they drop -on the slide 7', these va'recafrrie'd.to the :cylinder by gravitation and enter the cylinder'througrh the slot 31.` 'Ihe'cottonv is blown; through the` outlet O because of the" draft-created as is indicated `byV arrows' 12 to clean the topfaandk they partition 10,

lNhen the cottonis picked Aup by. the saws, the air suction takes it on outV through the 7C outletV O to gin the same.

1t is thought that the construction, utility' and advantages; of thisA inventioniwill now be quite appa-rent to those slril'le'clfin this art without a more detailed description'thereof. '-"5 ft is desired, howeven'to'point' out' that the shaft 22flni`aybe driven by belt 35 andpulley 36 and theauger 32 may be driven a belt and pulley ystructure 37 therefrom..

The present embodiment' of thev invention,

however, has been disclosed in detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. f

It is apparent that changes in the details 4of construction, and in the combination and belt in an orbit so that the upper run extends below the cylinder vand the saws, transverse cleatsl across the belt, means for inovingthe belt, a separator above the belt between the cylinder and the saws and inclining downwardly from the cylinders and the saws.

. 2. A machine of the .class described coml prising an elongated housing with a partition extending transversely thereacross, a plurality of rotary saws mounted in the housing below the partition, a screen separator cylinder journaled in the housing, a belt of the endless type, means for supporting the belt in an orbit so that the upper run extends Y below the cylinder .and the saws, transverse cleats across the belt, means for moving the belt, a separator above the belt between the cylinder and the saws and inclining downwardly from the cylinder and the saws, a plurality of spaced longitudinally extending cleatsformed on the lunder side of the separator plate, an upwardlyspring pressed roller under the upper run of the belt.

3. Armachine of the class described comprising an elongated housing with a partition extending transversely thereacross, a

plurality of rotary saws mountedin the housing below the partition, a screen separator cylinder journaled in the housing, a belt'of the endless type, means for supporting the belt in an orbit so that the upper run extends below the cylinder and the saws, transverse cleats across the belt, means for moving the belt, -a separator above the belt between the cylinder and the saws and inclining downthe bottom of the Vhousing inclining down- Y .i675 of the' cylinder being open to form anoutlet,

wardly fromrthe cylinder and the saws, a plurality of spaced longitudinally extending cleats formed on the under side of the separavtor plate, an upwardlyspring pressed roller and an auger rotatably mounted in the cylinder, means operatively connecting the auger with the means for driving the belt.

4. A. machine of the classdescribed comprising an elongated housing vwith a partition extending transversely thereacross, a

plurality of rotary saws mounted in the housing below the partition, a screen separator cylinder journaled in the housing, a beltof the endless type, means for supporting the belt in an orbit so that the upper runextends below the cylinder and the saws, transverse cleats across the belt, means for moving the belt, a separator above the belt betweenfthe cylinder and the saws and inclining downwardly from the cylinder and the saws, a plurality of spaced longitudinally extending cleats formed on the under side of the separa-V torplate, an upwardly spring pressed roller under the upper run of the belt, a portion of the bottomof'the housing incliningdownwardly and forwardly. and merging in a transverse cylinder with an entrance, one end of the cylinder being open to form an outlet,

and an auger rotatably mounted in the cylinder, means operatively connecting the auger with the means for driving 'the belt, a damper hingedly mountedon the forward end of the partition. y lntestimony whereof we aliixv our signatures. V o
